Therefore, a device cannot be uniquely identified by the BSS by using the minimum amount of information received with the initial access attempt, i.e. there is a risk that the second device has also included the same minimum amount of information in its initial access attempt

Embodiment Construction

[0028] Throughout the following description, where applicable, like reference numerals have been used to refer to like features, such as nodes, acts, steps, modules, circuits, parts, item elements, units, or the like. In the figures, features present in some embodiments are indicated by dashed lines.

[0029] As part of the development towards the embodiments herein, the context and issues indicated in the Background will be further discussed.

[0030] The payload to be transmitted is so small that all chunks are received in the response from the network ( figure 1 4 in ) was sent before ( figure 1 In the case of 3), the overhead increases significantly. In other words, the overhead (expressed as a percentage of the total payload space available within the full set of transmitted data blocks) represented by including a unique device ID in all data blocks transmitted prior to the receipt of the first response ) increases significantly with decreasing total payload.

Abstract

The invention relates to methods, wireless communication device and radio network node for managing contention resolution. Methods and arrangements for enabling contention resolution of uplink transmissions at a radio network node (120). A wireless communication device (110) sends (3010; 4010) an access request to the radio network node (120). The wireless communication device (110) receives (3040; 4040) an access grant from the radio network node (120) and then sends (3050-31 10; 4050-41 10), to the radio network node (120), at least two data blocks. At least two data blocks includes only oneoccurrence of a unique device identity and at least one occurrence of a reduced ID that is represented by fewer bits than the unique device ID.

Description

technical field [0001] Embodiments herein relate to wireless communication systems such as cellular networks. In particular, methods and corresponding wireless communication devices and corresponding radio network nodes are disclosed. Corresponding computer programs and carriers are thus also disclosed. Background technique [0002] With cellular technologies such as Global System for Mobile Communications (GSM) / Enhanced Data Rates for Global Evolution (EDGE), etc., cellular systems often operate using a fixed frame structure in time and well-defined channels in frequency. Scheduling of resources (ie parts of the frame structure) is typically handled by a base station or a node controlling a base station in a cellular network. An exception to this is typically on the Random Access Channel (RACH), where a user or mobile station (MS) makes an initial access attempt without being scheduled in the process of committing to receive a resource allocation. Consequently, multiple ...
